Question

hydrogen peroxide solution decomposes to form oxygen gas: 2H2O2 -> 2H2O+O2 .Calculate the volume of oxygen gas at rtp produced when 30cm^3 of 0.0200mol/dm^3 hydrogen peroxide decomposes to form oxygen gas. Molar volum e at rtp is 24000cm^3

pls help. will mark brainliest and give 5 stars ​

Answer 1

Answer:

Explanation:

equivalent=equivalent

molarity*volume*f=v/22.4*f

m=100 cm

0.1m=10cm

dm^3=10^3 cm^3

molarity = 0.02/1000

mvf=mvf

2*10^-5*30*1 = v/22.4*2

3*10^-4=v/22.4

v=6.72 ml or 0.00672 lt
